Natural hazards, such as earthquakes, volcanic eruptions, and tsunamis, have threatened human communities throughout recorded history. Scientists still face a long-term challenge to reveal the natural hazards' preparation process and precisely predict their occurrences. With space technology development, in the early 1980s, some satellites recorded abnormal electromagnetic emissions, plasma density irregularities, and energetic particle precipitations over active seismic fault zones, volcanic belts, or tsunamis coast. Since then, continuous efforts have been paid to the rock-rupture-processing experiment, ground-space comparative studies. Especially for earthquake science, the electromagnetic precursors might be the most promising tool for the short-term (timescale of hours, days, and weeks) earthquake prediction. In late 2004, France launched the DEMETER (Detection of Electromagnetic (EM) Emissions Transmitted from Earthquake Regions) satellite, which successfully operated from 2004 to 2010. In Febr. 2018, China launched the first seismo-electromagnetism satellite (China Seismo-Electromagnetic Satellite, CSES) aimed for earthquake monitoring from space.

We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.

Natural and human-induced changes in Earth's interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes requires a range of observations acquired from land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and USGS in developing these tools, the NRC was asked to carry out a "decadal strategy" survey of Earth science and applications from space that would develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015 and beyond, and present a prioritized list of space programs, missions, and supporting activities to address these questions. This report presents a vision for the Earth science program; an analysis of the existing Earth Observing System and recommendations to help restore its capabilities; an assessment of and recommendations for new observations and missions for the next decade; an examination of and recommendations for effective application of those observations; and an analysis of how best to sustain that observation and applications system.

The use of infrasound to monitor the atmosphere has, like infrasound itself, gone largely unheard of through the years. But it has many applications, and it is about time that a book is being devoted to this fascinating subject. Our own involvement with infrasound occurred as graduate students of Prof. William Donn, who had established an infrasound array at the Lamont-Doherty Geological Observatory (now the Lamont-Doherty Earth Observatory) of Columbia University. It was a natural outgrowth of another major activity at Lamont, using seismic waves to explore the Earth’s interior. Both the atmosphere and the solid Earth feature velocity (seismic or acoustic) gradients in the vertical which act to refract the respective waves. The refraction in turn allows one to calculate the respective background structure in these mediums, indirectly exploring locations that are hard to observe otherwise. Monitoring these signals also allows one to discover various phenomena, both natural and man-made (some of which have military applications).

As environmental problems move upward on the public agenda, our knowledge of the earth's systems and how to sustain the habitability of our world becomes more critical. This volume reports on the state of earth science and outlines a research agenda, with priorities keyed to the real-world challenges facing human society. The product of four years of development with input from more than 200 earth-science specialists, the volume offers a wealth of historical background and current information on: Plate tectonics, volcanism, and other heat-generated earth processes. Evolution of our global environment and of life itself, as revealed in the fossil record. Human exploitation of water, fossil fuels, and minerals. Interaction between human populations and the earth's surface, discussing the role we play in earth's systems and the dangers we face from natural hazards such as earthquakes and landslides. This volume offers a comprehensive look at how earth science is currently practiced and what should be done to train professionals and adequately equip them to find the answers necessary to manage more effectively the earth's systems. This well-organized and practical book will be of immediate interest to solid-earth scientists, researchers, and college and high school faculty, as well as policymakers in the environmental arena.

This book presents a unique, interdisciplinary approach to disaster risk research, combining cutting-edge natural science and social science methodologies. Bringing together leading scientists, policy makers and practitioners from around the world, it presents the risks of global hazards such as volcanoes, seismic events, landslides, hurricanes, precipitation floods and space weather, and provides real-world hazard case studies from Latin America, the Caribbean, Africa, the Middle East, Asia and the Pacific region. Avoiding complex mathematics, the authors provide insight into topics such as the vulnerability of society, disaster risk reduction policy, relations between disaster policy and climate change, adaptation to hazards, and (re)insurance approaches to extreme events. This is a key resource for academic researchers and graduate students in a wide range of disciplines linked to hazard and risk studies, including geophysics, volcanology, hydrology, atmospheric science, geomorphology, oceanography and remote sensing, and for professionals and policy makers working in disaster prevention and mitigation.

Space storms, the manifestation of bad weather in space, have a number of physical effects in the near-Earth environment: acceleration of charged particles in space, intensification of electric currents in space and on the ground, impressive aurora displays, and global magnetic disturbances on the Earth's surface. Space weather has been defined as `conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and atmosphere that can influence the performance and reliability of space- and ground-based technological systems and can endanger human life'. The 19 chapters of this book, written by some of the foremost experts on the topic, present the most recent developments in space storm physics and related technological issues, such as malfunction of satellites, communication and navigation systems, and electric power distribution grids. Readership: researchers, teachers and graduate students in space physics, astronomy, geomagnetism, space technology, electric power and communication technology, and non-specialist physicists and engineers. As recommended in the United Nations Space & Atmospheric Science Education Curriculum booklet. Please find it amongst classics such as T.J.M. Boyd, J.J. Sanderson, J.K. Hargreaves and M.C. Kelly etc.
